How to Make Soap

"Wow, Lu Zhe, you actually made a showerhead!"

"Let's try it out and see if it works well."

"Will it make our little hole wet?"

"We can place some banana leaves underneath to prevent that."

After laying down the banana leaves and creating a slight slope, the water could flow directly out of the hole.

Let's give it a try; success or failure hinges on this moment.

Several girls widened their eyes, witnessing this miraculous moment.

Lu Zhe pushed the bamboo pole forward, allowing the rainwater to fall into the bottle. The rainwater indeed entered, but the water didn't come down.

"It doesn't seem to work well."

"Don't worry, Lu Zhe. Adjust the showerhead a bit..."

Lu Zhe carefully inspected it and felt that the showerhead was made based on his own height, slightly too high. He trimmed it down a bit and made the water pipe shorter before trying again.

After waiting for a while, water started flowing out from the bamboo tube.

The water flow was too small, not splashing down but gathering at the bottom of the "showerhead" and dripping together.

It seemed that the showerhead was a bit of a failure.

But it was still not bad.

Let's test the water temperature. Initially, it was a bit hot to handle, probably because the water inside the gun barrel was heated for a bit too long.

After a while, the temperature went down and stabilized, reaching around 36 degrees Celsius, which was similar to body temperature.

"The length of the water flow through the stove is a bit short. If it were in a disc shape, the water would pass through the center of the stove, and it would probably reach a temperature above 40 degrees Celsius. That would be the most comfortable temperature."

"Why complain? Isn't this good enough?"

"Who would have thought that we, stranded on a deserted island, could have a water heater?"

"This is just the beginning. Once we find better resources in the future, many daily necessities can be further upgraded."

"Oh, Lu Zhe, what are these chunks that look like roasted food?"

"Don't you want to use soap for bathing? These are soaps!"

"Oh my, you actually made soap?"

Jiang Yao picked one up. It had already been dried out. She rinsed it with water and washed her hands. "It really lathers."

She smelled it, and there was a hint of lemon fragrance and a slightly fishy smell. "What did you use to make this?"

"Sago pearls, lemon, and bamboo charcoal!"

Shen Bing also picked one up and examined it, amazed. "It's the first time I've heard that these ingredients can be used to make soap!"

Lu Zhe smiled.

Now, here comes the question: Was this thing really made with these three ingredients?

Lu Zhe didn't lie; indeed, he included these three ingredients.

However, their roles were merely supplementary. Sago pearls were used for solidifying, lemon was used to mask the odor, and bamboo charcoal replaced lye as an alkali.

The real ingredients that gave it foaming and cleaning abilities were pig pancreas and some pig fat.

In the days before soap became popular, the older generation would use pig pancreas to make soap. They called it "pancreas"!

This thing had excellent cleaning capabilities, but if they were told directly that it was made from pig intestines, no one would dare to use it!

So... let's tell them after they finish washing!

"Now we can take a good bath!"

"Is it okay to use it for washing hair?"

"No problem!"

"Just think about it, I haven't thoroughly washed my hair in over twenty days, it's a disaster!"

"Hold on..."

At this moment, the girls realized a problem.

While it's great to have a bath, the location is inside the bamboo door of the whole small cave, which has the broadest view. If someone takes a bath, their companions can see everything clearly.

Could Lu Zhe have ulterior motives for doing this?

Understandable, are you a normal boy after all!

However...

Let's make a structure to cover it up a bit!

After all, girls need to maintain some modesty.

But we shouldn't block it completely; this is also the best opportunity to show off our figures.

Several girls quickly put together a simple bamboo frame with two bars, and they just need to drape their clothes over it, problem solved!

Lin Qianqian asked, "Should we wash in groups?"

Ning Shu annoyed, "Why group? Naturally, each person should wash individually. Also, Qianqian, can you not have that expectant look on your face like Lu Zhe?"

Lu Zhe innocently said, "Do I have it?"

Shen Bing smirked and said, "Alright, alright, just be careful."

As she said that, she balled up a piece of clothing and threw it onto Lu Zhe's shorts, covering the embarrassing area.

Lu Zhe looked at Shen Bing and said, "Actually, not showing any expression is the greatest disrespect to them!"

Two hours later, everyone finished bathing and returned to the bear skin, experiencing a completely different feeling.

"So refreshing..."

"It's only possible to get this clean with soap."

"But the scent is a bit strange."

"This soap won't last long; we need more. Hey, Lu Zhe, should we make some more?"

"We can't."

"Why?"

"Because we don't have enough pig pancreas."

With that sentence, all four girls were stunned. Shen Bing, being knowledgeable, also appeared a bit unnatural.

"What did you say?"

"Pancreas?"

"What's the pancreas?"

"I don't know, I've only heard of a horror anime related to the pancreas."

"That one is more of a healing genre, right..."

"That's right, it's a melancholic genre!"

"Anyway, it's one of the organs in a pig's body, which means..."

"We have to crush a pig's organs and smear them on our bodies while bathing?"

"Ah..."

After Jiang Yao said that, everyone immediately imagined themselves covered in bloody organ tissues, with a sinister smiling girl emerging from the blood-filled water...

"So... it's still us?"

"Please, noooo..."

However, Lu Zhe had already anticipated this reaction. He covered his ears and waited for them to finish shouting. Calmly, Lu Zhe said:

"There's nothing strange about it. Our grandparents' generation used this stuff to wash their faces and clothes. Let me tell you, it's much better for the skin than those face washes full of chemical elements."

Shen Bing recalled, "I remember now, my grandma seemed to have used this stuff, she called it... 'pancreas'!"

"That's right!" Lu Zhe said earnestly. "Although it's an animal's internal organ, it has strong cleansing power. In fact, it can even wash away the menstrual blood from the class leader's little bear!"

Ning Shu froze, feeling completely off.

Although the girls were still somewhat resistant, upon hearing that their grandparents used it to wash their hands, they gradually started to accept it.

"By the way, are we going to use it to wash from now on?"

Lu Zhe shook his head, "It's not a bad idea to use it, but we can only make a few bars of soap with one pig. If we want to have more soap, we can try some other methods!"

"What other methods?" asked Lin Qianqian.

She said, "Well, I know a method. We can boil pine needles to make soap, and if we add some flowers, we might be able to make scented soap."

Ning Shu sighed, "Aren't you afraid of ending up like a prickly hedgehog?"

She then asked Lu Zhe, "Does the '100,000 Whys' book mention this method?"

Lu Zhe checked the survival manual and found that there was indeed a method for making soap in the wild, but there was also a more scientific and professional way to make scented soap!

"Well, Qianqian's method is not bad. But it seems that there are no pine needles on this island. However, I have another better idea."

Seeing that Lu Zhe was about to do something, Tang Xiaoguo looked worried and thought for a moment.

"Brother Zhe, you... You're not going to use someone's poop to make soap, are you!"
